' Be'it known that'I, WVILLIAM'J. jBnisnn, a

citizen'of the United State's, and*residing at Port Richmond, county of'Richmond, State '5 of 'New York, have invented certain new and useful Improvements in Spring ."Wheels, of which the following 1s a specification;

This inventlon relates to springwheels ot that type particularly adaptedfor useon 10 motor vehicles. It embodies anovel anduseful combination including novel features of the hub structure disclosedand specifically claimed in my copending application Ser. No. 487,615, filed July 26, 1921;andnovel 1 features of a rim structure adapted tore from the following description and-claims, 5 taken with the accompanying ClI'QWIDgSL J In the-drawings Fi 1 is a side view ofa'wheel embodying the invention, the rim stru'cture'being l shownpartly in section and portion of the 2o hub cap being shown removed.

the curvature" ofthe-p'art beyond the offset Q" 15 is such as to adapt 'it to fit the innenTsur face of the rim,-it may when made andbe that it will be under' somefterision pressing outward when the wheel is assembled. It has been found that this longitudinal curvature tci the spring gives especially good results in resiliency and lasting qualities and also gives all. of? the requisite strength.

Referring now to the hub structure the inner radial ends 13 of the spokes have rectangular side notches 17. A pair of circular disks 18 having central openings48 fitting the cylindrical portion 12 of the hub have aligned radial slots 46, and 4:7 in their outer and inner edges corresponding in width to the thickness of the spokes with a solid portion 19 between the ends of the slots of such size as to f t in the rectangular notches-l7 Of the, spokes with the adjacent edges of the spokes resting the radial slots. A flange or circular disk 20 slides over the end of cylindrical portion 12 and lits the sides of the spokes and one ofthe disks 18 while, the other sides of the spokes and the other disk. 18; fit integral flange 11." Bolts with nuts 21 pass through the flanges and disk be-' tween spokes and secure them together on the hub. This huh structure is like. that in my application Ser. No. 487 615 and permits detaching the wheel from the hub.

The preferred form of rim'structure and cooperating end structure of the spokes are shown in Figures '1 and 2. The inner rim 22. is channelshaped facing inward and is centinuous. An outer channel shapedfirim 23 facin outwardly and slightly wider than rim 22 ts the outer surface 0t rim 22 and has its inner flange 24 of greaterrheight than its outer rfii nge25 and its outer edge is trans.-

Versely curved outwardly as shown at 26. The. outer edge 27 of flange 25 is transversely curved similarly to the outer edge26. The

outer ends 29 of thejspokes beyond oflset 15 closely fit the inner surface of thebase of the channel rim 22'between its side flangespand the side flanges turnish lateral supports for thegends of the spokes Bolts. 30 or othersuitableffastening Incanspass through the end portions 29 of the. spokes the base of channel rim 22- and the base ofchaunel rim 23 and securely hold them together, Bolts 31 having screw threaded nuts pass through the side flanges 2a and 25 of channel rim 23 and, also through retaining clips 32 which have a depending portion adapted to fit the Outer and. under side of flange 25 and an upper inwardly curved portion 33 above'the outer edge of flange 25. The flange 25 being,

nection between the ends of the spokes and the channel rim, other means may be used in combination with the two channel rims the outer of which serves to receive a detachable rim. In Figure 3 for instance is shown a form of connection where a part of the end of the outer portion 16 of the spoke is curled transversely in cylindrical form 34 surrounding a bolt passing through the side flanges ofthe inner channel rim 22 thus securing the spoke to the rim. In this case projecting'portions 36 and 37 make contact with the inner surface oi": the base of channel rim 22 so as to preventrattling. In Figures & and 5 another form is shown where the end of portion 16 oi the spoke is provided with perforated side ears 38 which are bent at right angles and a bolt 89 passes through them and through the side flanges of inner channel rim 22? the projecting 'end or" the spoke bearing against'the inner iace of the base of the channel.

In Figures 6, 7v and '8 l have shown a modified form of inner channel bar rim and a modified form of spoke end to ht it and have also shown an added element in the form of a contlnuous ring interposed be tween the two channel bar runs, In this 7 instance the inner rim to has a narrow channel 41 facing outwardly and laterally eX- the point 43 in Figure 8 and the projecting narrow portion 44 is benttransversely on longitudinal lines to right angles and fits over the inward projection formed by the narrow channel 41 of rim il). 'Thislateral bending of the narrow portion of the spoke extends somewhat beyond the point 13 but the widerf portions of the spoke are gradually bent outward lessening the central longitudinal depression and" bringing all parts of the spoke into transverse alignment or into the same transyerse plane near the rim. Bo1ts45. pass through the lapping sides of portion 44: the walls of'channcl 41 and ring 42 thereby'rigidly securing the ends of the spokes to the-inner rim and ring 42. Itwill be noted that in this form as well as that of Figures 1 and 2 the outer ends of the spokes closelyv fit the inner portions of the inner channel bar rim and are rigidly bolted to it.

The structure ofthe rim and ends of the spokes, and the means for securing them together shownin Figure 9 are identical with What is shown in Figure 1 except that the LLLC 45 the rim.

each composed of a single strip of metal is shown for illustration, the invention 18 not limited as to the number of spokes or the number of layers of which they are cornposed' and is not limited to any of the details shown'beyond what is indicated in the claims.
